The short answer

Assess Safety First

Before touching anything, confirm the fire is completely out and the structure is stable. The fire department or a qualified inspector should give you the all-clear. If you smell gas or see charred wires, leave and call for help from outside.

You also need to consider your own health. Smoke residue can irritate your lungs and skin, so wear an N95 mask, gloves, and long sleeves. If you feel dizzy, nauseous, or have trouble breathing, stop and see a doctor.

What You Can Clean Yourself

For a very small fire, you can often wipe soot off hard surfaces like countertops, tile, glass, and metal. Use a dry sponge or a cloth with a mild degreaser, working from top to bottom. Change your cleaning water often so you do not smear the soot around.

You can also wash washable fabrics like curtains and clothing, but check the care label first. Small items like dishes and pots can be washed in hot, soapy water. If an item has a strong smoke smell after washing, it may need a different approach.

  • Wear an N95 mask and gloves at all times
  • Open windows for ventilation while you work
  • Use a dry chemical sponge for loose soot
  • Clean hard surfaces from top to bottom
  • Wash fabrics only if the label allows it
  • Discard porous food or burnt packaging

When to Stop and Call the Pros

Some areas are simply not safe or practical for a homeowner to clean. Soot can travel deep into wall cavities, insulation, and air ducts, leaving a smell that returns for months. Electrical outlets and light fixtures should only be handled by an electrician.

If soot has touched upholstery, carpet, or mattresses, home cleaners often miss the residue trapped deep in the fibers. These materials hold smoke particles and require specialized equipment to remove the odor. The pros have industrial vacuums and cleaning agents made for fire residue.

  • Soot inside air ducts or HVAC systems
  • Smoke odor lingering after your sensible effort
  • Charred drywall, insulation, or wood framing
  • Upholstered furniture or carpets with heavy soot
  • Any electrical component touched by heat or smoke

Air Ducts and Deep Cleaning

After a fire, even a small one, smoke can settle in your heating and cooling system. Running the system before cleaning it can push soot through the whole house. That is why air duct cleaning is often part of the recovery process.

A professional duct cleaning can remove soot and debris from the entire system. This is a job for someone with the right tools and training, not a DIY project. If you live in Kirkland, you might want to schedule this before turning your heat back on.

Insurance and Documentation

Before you start cleaning, take photos of the damaged areas and any items you plan to discard. Your insurance company may ask for documentation to process a claim. Keep receipts for cleaning supplies and any items you replace.

Policies vary, and your insurer decides what is covered. Some policies cover professional cleaning, while others may only reimburse you for your own supplies. Ask your insurance company what documentation they need before you throw anything away.

Frequently asked questions

How long does smoke smell last in a house?

It depends on how much soot got into porous surfaces and airflow. Without proper cleaning, the smell can linger for weeks or months. The pros use specialized equipment to neutralize odor at the source, which is often the only way to get rid of it completely.

Can I clean soot off walls with just water?

Plain water often smears soot and makes the stain worse. Use a dry chemical sponge first to lift loose soot, then a mild degreaser or soapy water. Test on a small, hidden area first to make sure the cleaner does not damage the paint.

Should I throw away burned food or containers?

Yes, throw away any food that was near the fire, especially if the packaging is charred or melted. Smoke can permeate sealed containers, so when in doubt, discard it. If you are unsure about a large pantry, ask your insurance company about coverage for food loss.
